Extreme Weather Warning Now in Effect for Halton

If so, you're not alone—and you're probably going to get even toastier.

Environment Canada recently announced that a heat warning is in effect for Mississauga, Brampton, Caledon, Oakville, Burlington, Milton and Halton Hills.

The agency also said that an "extreme heart event" is in the forecast for the Canada Day long weekend.

Environment Canada says that beginning Friday and continuing through the long weekend, daytime highs are expected to reach the low to mid thirties with humidex values into the mid forties. Overnight low temperatures will only fall to the low to mid twenties (and the high teens in some rural areas).

"Current indications suggest hot temperatures could persist through next week. This will be the most significant heat event in the past few years," the agency writes.

While extreme heat poses greater risks for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors, it can affect anyone.

Anyone who is spending time outdoors should watch for the effects of heat illness, including swelling, rashes, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

People should check on vulnerable friends and family members and bring pets indoors.

Although it should go without saying, it is extremely dangerous to leave children, pets and vulnerable people inside parked cars for any period of time.
